2 Claims.

condition; to provide a unit assembly of the kind indicated in which the connection between the tank and closet is such as to oppose any twisting or turning of the former on the latter with the attendant probability of loosening the water connections with consequent leakage; and to provide a combined closet and tank in which the ush valve and attendant parts may be of standard make, so that the tank and closet as a whole may present the simplest form of construction and may therefore be manufactured at a minimum cost.

With this object in view, the invention consists in a construction and combination ofparts of which a preferred embodiment is illustrated in the accompanying drawing, wherein:

Figure 1 is a side elevational view of a combination unit constructed in accordance with the invention.

Figure 2 is a vertical sectional view on the plane indicated by the line 2-2 of Figure 1.

Figure 3 is a detail sectional view on the plane indicated by the line 3-3 of Figure 2.

Figure 4 is a perspective view of the conical washer employed in connection with the flush valve outlet.

In carrying out the invention, the closet 10 is molded to provide a rear shelf or support 11 for the flush tank 12, this shelf being bounded with an upstanding rib 14 throughout its perimeter. Those portions 14a of the rib which bound the back edge and ends of the shelf 11 are of less height than that portion which bounds the front edge of the shelf, so that the tank, when seated on the shelf will bearupon the upper edge of the front but will" be spaced from the rear and end ribs 148. f v

The shelf 11 is provided with a central opening 15 in communication with the flushing channels of the closet, which opening is of sufficient diameter to provide a body hole for the threaded thimble or sleeve 16 of the flush valve equipment 17, this sleeve being passed through a body opening in the bottom of the tank 12 with the shouldered portion 18 consisting of a compressible washer 19. A similar compressible washer 20 is disposed in surrounding relation to the sleeve 16 on the under face or bottom of the tank and the clamp nut 21 threaded on the sleeve is brought up tight against this washer, so that the shouldered portion of the sleeve. and the nut 21 function to compress the two washers 19 and 20 against the inner and outer faces of the bottom wall of the tank and positively preclude leakage of water at these points.

Seated against the under face of the nut 21 is a against the periphery of the hole or opening 15 at the upper side thereof.

By means of this construction, when the tank is seated on the shelf and the ush valve is open, water from the tank may be discharged into the flushing channels of the closet through the tlnible or sleeve 16, the lower end of whichextends below the plane of the shelf 14 and the conical washer 22 surrounding which precludes any leakage onto the upper face of the shelf.

The means for securing the tank in position on the shelf consist of the bolts 23 which are of the button-head type, passed through holes in the bottom wall of the tank. Compressible washers 25 are interposed between the heads of the bolts and the top face of the bottom wall of the tank and clamping nuts 25 are threaded onto the shanks of the bolts and bear against washers 26 (preferably brass) which bear against the under face of the bottom wall of the tank. 'I'he b olts are thus rigidly secured to the bottom wall of the tank and with leak-proof connections by reason of the Compressible washers l25. 'I'he shelf 14, on either side of the opening 15, is formed with holes in axial alignment with the holes in the tank in which the bolts 23 are mounted and when .the tank is seated on the ribs of the shelf, the shanks pass through these holes in the latter to terminally receive the nuts 27 conical washer 22 whose slanting sides bearv which may be of any suitable form but are preferably wing or thumb nuts bearing against metallic washers 28 which in turn bear against resilient washers 29 which latter washers bear against the under face of the shelf. 'I'he tightening of the wing nuts thus eiectively secures the tank in position on the shelf and precludes any tendency of the latter to turn or twist with the flush valve sleeve as a pivot which would in all probability result in loosening the sleeve and thus providing for leakage where the ush valve is mounted in the tank.

Disposed in straddling relation to the rear rib 14 of the shelf are U-shaped cushion members 30 against the web portions of which the bottom wall of the tank bears and compresses when the nuts 27 are tightened. By reason of this conso I,

struction, when the tank is brought down into firm contact with the upper edges of the front and rear ribs, the cushion members 30 are com- Vpressed'and thus comprise a resilient medium to hold the tank in place to preclude its being shaken loose and to nterpose a frictional resistance against any tendency to turn the tank with the sleeve 16 as a pivot. f

The invention having beendescribed, what is claimed as new and useful is:

1. A unit combination of the kind indicated comprising a'closet having a rearwardly extending shelf provided with a peripheral rib bounding the same, a tank seated on the upper edge of said rib, flush Valve equipment mounted in the tank andilhaving Ya thimble extending through'the bottom wallgthereof and through anV opening in the shelf to be in communication with the flushing channels of the'closet, bolts mounted in the bottom wall of the closet on diametrically opposite sides of said thimble and passing through openings in the shelf, and removable fasteners secured to the lower ends of the bolts and bearing against the under face of the shelf, those portions of the rib bounding the back edge and ends of the shelf being of less height than the YYfront portion, and U -shaped members of resilient material disposed in straddling relation to the reduced portionY of therib and bearing against the under face of the bottom of the tank. l'

2. A unit combination ofthe kind indicated comprising a closet having a rearwardly extending shelf provided with a tank seat, a tank mounted on said seat, a ush valve equipment mounted in the tank and having a thimble extending through the bottom wall thereof and through anY opening in the shelf to be in communication with the flushing channels of the closet, an annular fastener embracing the thimble to secure it to the tank, fasteners carried by the tank and'disposed upon diametrically opposite sides but spaced from said thimble and passing through openings in the shelf, and an in verted frusto-conical compressible gasket surrounding the thimble and seated against the fastener with its slanting wall entering the opening in the'shelf for compression atY the peripheral edge of said opening upon tightening of said fasteners to engage the tank with the seat, the thimble being unconnected with the shelf except to pass through the opening thereof.
